    -Jennifer Langdon from Glen Head, NY

    I have experienced other vets over the years w/ my 1st dog Harley an English Mastiff who is absolutely frightened of vets. Every time we went to a vet he would make a small grawl noise as protest. Our last vet would just muzzle him. We switched to Glen. When I brought him there he did the same thing but instead of muzzling him the wonderful vets there took 45 mins down on the floor w/ him to get to know him and make him feel comfy... no muzzle needed. I love their caring, compassion and knowledge...

    -Cash's Moms from Bayville, NY
    Pet Name: Cash

    Pet Image We got our first puppy 2 years ago and promptly realized we had no idea what to do with him! He is a rare breed and we had so many questions. We found Glen Animal Hospital and fell in love almost as fast as we did with Cash! They helped us through all the new puppy things and never minded how many times we called with questions. I love knowing that Cash is getting the best care out there.
